提示下边越界，怎么修改才行呢

Private Sub LoadHouse()
Dim n As Integer
Dim n As Integer

For n = MSFlexGrid1.Rows - 1 To 2 Step -1

MSFlexGrid1.RemoveItem (n)

Next

Dim str As String
If m_kind = "全部" Then

str = "select * from 客房信息表 order by 客房ID"
Else
str = "select * from 客房信息表 where 类型 ='" & m_kind & "'order by 客房ID "

End If

Dim myrs As ADODB.Recordset
Set myrs = New ADODB.Recordset

myrs.CursorLocation = adUseClient
myrs.LockType = adLockOptimistic
myrs.CursorType = adOpenDynamic
myrs.Open str, cnn
myrs.MoveFirst

Dim m_sum As Integer '读取共多少条记录

m_sum = myrs.RecordCount
MSFlexGrid1.Rows = MSFlexGrid1.Rows + m_sum - 1

Dim m As Integer

For m = 1 To m_sum

MSFlexGrid1.TextMatrix(m, 1) = myrs("用户名")
MSFlexGrid1.TextMatrix(m, 2) = myrs("职位")
MSFlexGrid1.TextMatrix(m, 3) = myrs("密码")

myrs.MoveNext

Next

End Sub

一定是列或行数多与数据库里的列值.
数据库第一列为0列.第二列才是1...依次类推...
